GAS-BURNER.

$PE'CIFIGATION forming part of Letters Patent No. 783,919, datedFebruary-28, 1905.

Implication filed July 23, 1904. Serial No. 217,785

To all "in/"mm it nmy concern:

Be it known that 1, JOHN F. Youo, a citizen of the United States,'and aresident of Seattle. 'W'ashington, have invented certain new and usefulImprovements inGas-Burners, of which the following is a specificationcontaining a full, clear, andexact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention -relates to improvements in gas-burners; and it consists ofthe novel features herein shown, described, and claimed.

In the drawings, Figure 1 is a vertical-central section on the linel 1ofFig. 2. Fig. 2 is a horizontalflsection looking downwardly on the line2 2 of Fig. 1. Fig. 3 is a bottom plan view of the upperburner-receptacle, as indicated by the'arrow 3 in Fig. 1. Fig. 4 is abottom plan view of the intermediate burnerreceptacle, as indicated bythe arrow 4 in Fig. 1.

Referring to the drawings indetail, I have shown my improved gas-burnerlocated for operation in an air-tight receptacle adapted for heatingwater; but it should'be understood that the burner may be used in otherconnections.

The burner comprisesthe lower upwardlyflanged receptacle 5; theintermediate upwardly-flanged receptacle 6, having spacingblocks 7 toengage the lower receptacle and form the gas-opening 8; therivets 9,connectmg the lower andintermediate receptacles to-' gether; thegas-pipe 10, leading throligh the. intermediate receptacle andsupporting the burner; the upper upwardly --flanged receptacle 11, therebeing spacing-blocks 12 extending upwardly from the upper edge of theintermediate receptacle to engage the upper receptacle and" form theair-opening 13, be-

tween the intermediate receptacle and the upper receptacle, and formingthe mixing-chamber '14:, between the upper receptacle and the tacle" 11.A globe-valve 16 controls the passage of gas to the burner, and apilot-light pipe 17 leads from the gas-pipe around the globe-valvedownwardly through the top of the water-heater to a point near theburner, the object being to allow the pilot-light to burn continuously,so that when the valve 16 is opened the burner will light from thepilotlight. A door 18 through the wall of the air tight combustionchamber within the water-heater provides means of lighting the burnerthe first time or at any time that the pilot-light may becomeextinguished.

As soon as the burner is 'lightedcombustion takes place aroundv theair-pipe 15, thereby heating the air in said pipe, and the suctioncaused by the combustion will draw the cold air downwardly into the pipeand the hot air from the lower part of the pipe outwardly through theair opening 13 and throughthe mixing-chamber 14. The gas passing throughthe gas-opening 8 will mix with the air passing through the air-opening13 into the mixing-chamber, and the air and gas will. be discharged intothe combustionchamber ready for burning.

The water-heater forms, as before sug gested,,an air-tight receptacle,and the air pipe.15 serves as a vent to supply the burner with air, andthe combustion around the airpi'pe heats, the air and increases thedraft. The products of combustion pass from the Combustion-chamber .inthe air-tight recep-I tacle upwardly and outwardly through the flue 19.

l'claim 1. In a gas-burner: a lower upwardlyflanged receptacle; anintermediate upwardlyflanged receptacle located in the lower receptacle;an upper upwardly-flanged receptacle seated in the intermediatereceptacle; a gas supply pipe-extending into the space between the lowerand intermediate receptacles; and

an ainsupply pipe extending into the space between the-upper andintermediate receptacle's; substantially as specified.

2. In a gas-burner: a lower upwardlyflanged receptacle; an intermediateupwardlyflanged receptacle located in the lower receptacle; an upperupwardly-flanged receptacle seated in the intermediate receptacle; agassupply pipe extending into the space between the lower andintermediate receptacles; an air-supply pipe extending into the spacebetween the upper and intermediate receptacles; and means whereby theair supplied by the air-supply pipe is heated; substantially asspecified.

3; The combination of a gas-burner com-- prising a lowerupwardly-flanged receptacle; an intermediate upwardly-flanged receptacleseated in the lower receptacle; an upper upwardly-flanged receptacleseated in the intermediatereceptacle; agas-supply pipe extending intothe space between the lower and intermediate receptacles, with anair-tight recepta'cle having a vent at its top; said gasburner beingseated in said air:tight receptacle; and an air-pipe leading from saidvent to the space between the upper and intermediate receptacles;substantially as specified.

4. In a gas-burner: a lower upwardlyflanged receptacle; 'an intermediateupwardlyflanged receptacle seated in the lower receptacle andforming agas-discharge opening; an upper upwardly-flanged receptacle seated intheintermediate receptacle and forming an air-discharge opening betweenthe intermediate receptacle and the upper receptacle and forming the gasand air mixing chamber between the lower receptacle and the'upperreceptaclepmeans of leading the gas to the gas-discharge opening; andmeans of leading air to the, air-discharge opening and to themixing-chamber; substantially as specified.

5. In a gas-burner: a lower upwardlyflanged receptacle; an intermediateupwardlyflanged receptacle located in the lower receptacle; an upperupwardly-flanged receptacle seated in the intermediate receptacle; agassupply pipe extending into the space between the lower andintermediate receptacles; an air-supply pipe extending into the spacebetween the upper and intermediate receptacles; means whereby the airsupplied by the airsupply pipe is heated; and a pilot-lightbu-rneradjacent to themain burner; substan- I tially as specified. n

In testimony whereof Ihave signed my name to this specification inpresence of two subscribing witnesses.

JOHN F. YOHO.
